Hello Lauri!
RSForm! Pro is using JMailHelper::isEmailAddress() function to validate the email address. The actual problem lies there. This solution worked just fine with me:
- Open libraries/joomla/mail/helper.php file
- Find function isEmailAddress()
- After the $domain_array has been defined apply the lines you can see here below...
// Check the domain DO NOT TOUCH THIS
$domain_array = explode(".", rtrim( $domain, '.' ));
$regex = '/^[A-Za-z0-9-]{0,63}$/';
// APPLY THE CODE BELOW
// check that domain consists of at least two parts separated by a dot
if ( sizeof($domain_array)<2 )
{ return false; }
// Check that the last part in the array is longer than 1 but shorter than 4
if ( strlen( end($domain_array) )<2 || strlen( end($domain_array) )>4 )
{ return false; }
